Abstract

In this study, we investigated the potential of Resina Pini (RP) for anti-inflammatory and analgesic agents to treat inflammatory diseases such as gingivitis and periodontitis. Crude RP (RP1), recrystallized RP (RP2), and Ramus Mori Albae-treated RP (RP3), plus their respective water extracts (RP1-WE, RP2-WE and RP3-WE) were prepared for in vitro and in vivo tests. We couldn’t find any signs of heavy metals pollution in all the RP samples. RP2-WE exhibited the highest viability of human gingival fibroblasts (HGF) and the strongest scavenging activity on superoxide anion. RP1, RP2 and RP3, RP2 showed potent scavenging activity on DPPH free radical. RP2-WE displayed a stronger inhibition on hyaluronidase (HAase) activity and RP3 also displayed potent HAase inhibition. RP2-WE, RP3-WE, RP3 and RP2 were reduced admirably the production of PGE₂ in HGF. In addition, RP2-WE and RP3-WE exhibited potent inhibitory activities on arachidonic acid-induced ear edema in mouse. Moreover, RP-2 prevented completely acetic acid-induced writhing by 100.0% and RP1, RP3, RP1-WE and RP2-WE also exhibited excellent protective activities against writhing. While aminopyrine, the positive control, showed 76.9% analgesic effect at the same dose. Taken together, these results suggest that recrystallized aqueous extract of Resina Pini could be a promising drug for the treatment of periodontal diseases.
